Quick Start Guide for i.MX28 EVK
i.MX28 EVK
Multimedia and connectivity
The i.MX28 EVK is designed for
multimedia and connectivity applications.
These applications use the i.MX28 series
ARM9™ applications processor. The
i.MX28 EVK can be used as a hardware
and software development platform. This
decreases time to market and provides a
near-to-final product design. The board
support package (BSP) for the i.MX28
EVK contains drivers optimized for
multimedia operations using the i.MX28.
The following features are available
in the i.MX28 EVK board:
• i.MX28processor

Getting Started
This section describes how to use the i.MX28 Kit EVK and the
components in the EVK. This section also describes the PC requirements
to develop applications using the i.MX28 EVK.
Unpacking the Kit
The i.MX28 EVK is shipped with
the items listed in Table 1.
Ensure the items listed in Table 1 are
available in the i.MX28 development
kit. Remove the EVK board from the
antistatic bag and perform a visual
inspection.

NOTE:
The4.3”widescreenvideographicsarray(WVGA)LCD
board is an optional card for the i.MX28 EVK board and
it is sold separately from the i.MX28 EVK board.
The i.MX28 EVK board is
connected to the add-on
LCDboardusing120-pin
surface mount connectors.
The connectors are
keyed to avoid incorrect
connection. Therefore,
there is only one way to
connect the boards. The
LCDboardisconnected
to the J78 connector. The
J78 connector is located
on the top of the i.MX28
EVK board as shown.
